# AdBlue in a Diesel Tank in Eastcote Village? Don't Start It

Engine off, ignition off: that is where you start if AdBlue has gone into your diesel tank.

Chemically, AdBlue is just urea in water.

The trouble starts once it is pulled through your pump — it won't burn, and it won't combine with diesel.

Caught before the motor has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where your car is around Eastcote Village.

Before anything, call us on 0333 366 0103.

## Eastcote Village, AdBlue in your diesel tank: what to do straight away

Do these:

- Pocket your keys, which prevents anyone turning the electrics on.

- Put your hazards on if you are anywhere close to moving traffic.

- The empty bottle or your receipt tells us the fluid and the amount, so do not throw it away.

- Tell us a postcode starting HA5 2, or whatever street lies nearest, and our van finds you directly — so call wherever you are.

Never:

- Don't start the engine, even for a moment to shift the vehicle.

- Switching the key to ignition by itself starts your pump running on many diesels. Avoid it.

- Do not top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out.

- Any driving at all is to be avoided, including a short way up Flag Walk.

- Beside the road, don't attempt draining it yourself.

Moving your car away from the pumps is a job for attendants to help with, wherever Eastcote Village forecourt you are on, the the nearest petrol station included.

If you are on your own drive, leave it exactly where it is.

## What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not your engine.

Kept in a separate tank, it is injected into the exhaust stream to clean the gases.

Nothing in an injection pump is designed for this fluid — and no part of that was meant to travel through one.

Poured in with the diesel, it keeps apart instead of mixing — quite unlike fuel.

It sinks, because it's heavier than diesel, and pools down where the intake draws its supply from.

A motor topped up on a drive in Northwood Hills overnight and not started since counts as the straightforward case. No pump has pulled the AdBlue up so far — though once the motor runs, that is what is pulled first, straight from the bottom of the tank.

After it is drawn in, the damage takes two forms.

What is left when the water evaporates is urea, which turns into crystals: they lodge in narrow channels and clog filters. On top of that, it eats at some metals in a fuel system, and keeps going till it is cleared out.

If the AdBlue has reached the lines, leaving it overnight in Eastcote Village leaves it worse. Inside the tank only, waiting costs nothing.

Water protects nothing. The injection pump and every injector need diesel running through them, and so the water part damages them in its own right.

## Why AdBlue in a diesel is frequently more major than petrol

Petrol put into a diesel on Esso's forecourt leaves the fuel thin — that's the whole fault.

Damage just comes from driving on it. Blended into your diesel and sitting in the tank, it does nothing.

With AdBlue in a diesel, the fluid itself is simply the wrong one.

Not burning, it can't simply be run through.

Nor can it be thinned, since it splits again — and the next fill will not clear away crystals or corrosion. So the flush matters more with AdBlue, and turning the key "to see", in the heart of Eastcote Village or out in Pinner, costs more than nearly any other slip.

The same good news applies as with petrol.

Not run? Then the AdBlue waits just inside your tank, the easiest section of the entire system to clear, wherever the vehicle has come to rest in Greater London.

## AdBlue in a diesel tank in Eastcote Village: how it ends up there

After dark, two caps side by side — the AdBlue cap and the diesel cap, occasionally under a single flap — may appear the same. No one means it; many designs allow it.

Usually it is never the filling station: a driver picks up a bottle heading home and tips it in at home.

The ways it happens are few and familiar.

Hurrying, outside Coteford Infant School, after a warning light came on during the school run, a parent tops up the car.

A bottle is poured in at the end of the day on a drive just off High Road Eastcote.

Or someone new to that flap refills your vehicle in dim light, parked in the car park by The Case Is Altered.

Rented vehicles, new vehicles, company motors, or the spare car in a family with both fuels: the least familiar cars get it most.

Keep it switched off: that's the first response to the same mistake, anywhere around Eastcote Village or the remainder of Greater London you happen to be.

## Eastcote Village: started your engine with AdBlue in the diesel tank?

Then the tank is no longer where the AdBlue is.

Through your filter, along the lines, and — given any running time — on to the high-pressure pump and each injector: that's how far it travels.

You may see your engine running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Enigma Square or halfway across Eastcote Village.

Stop when safe. Turn off. Keep it off rather than testing it again.

With each start, more of it is pulled through.

Eastcote Village sits under 5 miles from the M40; if you were on it, leave at the next junction and pull up safely instead of carrying on.

A quick hop across Eastcote Village to the car park by Eastcote Methodist Church is one thing; driving towards St Albans, under 15 miles away, is something else, because every mile carries the AdBlue deeper in. So mileage counts.

Tell us about how far it had come.

Once the motor has been run, the flush includes more, and all of it is done where your car has ended up.

Very rarely does it leave long-term damage if it is caught early.

## What does an AdBlue drain on a diesel involve in Eastcote Village?

Anywhere it has stopped in Eastcote Village — a filling station, a layby, a drive, a street by Pembroke Park Community Centre — the van travels to the vehicle.

The job rests on three replies, which our engineers ask for first — which fluid got in, the quantity, and whether your engine has turned over.

Next, emptying the tank on the spot removes the contaminated diesel and the AdBlue together.

Residue from AdBlue will not flush out by itself, and so the fuel system gets a careful flush, which matters much more with urea than for petrol.

Next, the fuel filter: flushed, or replaced if it must be. Then clean diesel, then a check of your vehicle.

The majority of these jobs are a half-hour visit once our technicians turn up, provided the motor has not run.

The equipment is explosion-proof, and so a live forecourt is no fault, and it's quiet enough for a residential street after dark.

New diesel goes in to prime the fuel system, and that's the final step.

Whether it's a parking space by West Ruislip or a drive around Eastcote Village, that is where our engineers fire it up and you head off.

The check before our engineers go is that it runs smoothly on clean diesel.

The whole job is done where the vehicle is, so it never needs to go to a garage.

At the end, you are given the paperwork for the insurer: a VAT invoice plus a report from the engineer.

## AdBlue drains across Greater London, Eastcote Village included

AdBlue call-outs around Eastcote Village are passed to teams that serve the places around it — Eastcote, Ruislip as well as Ruislip Manor — and most of Greater London further out, throughout HA postcodes.

If you're close to a border, or somewhere hard to explain, ring and ask instead of assuming.

A van that comes to you fits Eastcote Village, a small village: there's no need to take the vehicle to us, because our technicians empty it on the spot, on a driveway, a residential street, a car park or a forecourt.

## Eastcote Village: what AdBlue in a diesel tank costs to fix

There is no fair single quote, because the jobs aren't the same.

Three things move the cost: whether the engine has been running and for how long, how much AdBlue went in, and where the car is. That last one rests on whether a technician can get to it safely, and an open driveway is simpler than a tight space behind St Thomas More.

For that in mind, every enquiry from Eastcote Village opens by asking the identical trio — which fluid went in, how much, if the engine ran — ahead of any figure.

Once those are known, a range becomes a single fixed figure.

The quote is given during the call, before anyone sets off; payment happens on the day, by card or over the phone, and nothing upfront.

Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.

## Still next to the vehicle around Eastcote Village?

Then, touch nothing — that's the most helpful step there is.

Ignition off, motor off, keys out.

Phone 0333 366 0103: AdBlue, the amount, plus whether the engine ran is all our technicians ask. Petrol in Diesel handles the remainder across Greater London, Eastcote Village too.
